NVIDIA invests $2 billion each in Lumentum and Coherent to scale silicon photonics for AI infrastructure. LITE stock jumps 12% on the news.
NVIDIA is betting $4 billion on optical technology to power its next generation of AI data centers, splitting the investment equally between Lumentum Holdings (NASDAQ: LITE) and Coherent Corp. (NYSE: COHR) in parallel deals announced March 2, 2026.
The nonexclusive agreements give NVIDIA multibillion-dollar purchase commitments and future capacity access rights for advanced laser components. Both optics specialists will use the capital to expand U.S.-based manufacturing and deepen R&D collaboration on silicon photonics—the technology NVIDIA sees as essential for building what it calls “gigawatt-scale AI factories.”
Why Optics Matter for AI Scale
As AI models grow larger, moving data between chips becomes a bottleneck. Optical interconnects transfer information using light rather than electrical signals, offering higher bandwidth and better energy efficiency—critical factors when you’re trying to cool a data center that consumes as much power as a small city.
NVIDIA and Lumentum aren’t starting from scratch here. Lumentum was selected as an NVIDIA Silicon Photonics Ecosystem Partner in March 2025, with its high-power lasers already integrated into NVIDIA’s Spectrum-X Photonics and Quantum-X Photonics networking switches.
Market Reaction and Lumentum’s Trajectory
LITE shares jumped approximately 11.77% following the announcement. The stock has been on a tear—up nearly 900% over the past 12 months as AI infrastructure demand accelerates.
That momentum shows in the fundamentals. Lumentum posted record Q2 fiscal 2026 revenue of $665.5 million, representing 65.5% year-over-year growth. The NVIDIA investment will fund a new fabrication facility to meet what both companies expect will be sustained demand from AI data center buildouts.
The Bigger Picture
NVIDIA’s dual investments signal that optical interconnect technology has moved from “nice to have” to mission-critical for AI infrastructure. By backing two suppliers rather than one, NVIDIA hedges supply chain risk while ensuring competitive pressure keeps innovation moving.
For traders watching the AI infrastructure theme, the photonics supply chain just became a lot more interesting. Lumentum’s next earnings call should reveal whether the $2 billion commitment translates into meaningful capacity expansion timelines.
